IRONING-MACHINE.

Specification of Letters Patent.

Application filed June 29, 1908.

Patented April 20, 1909.

Serial No. 440,874.

To all whom it may concern:

Be it known that I, Go'rTLoB FEEDERIOK KUHNLE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Ironing-Machine, of which the following is a specification.

This invention relates to a new and novel ironing machine and has for an object to provide an iron which is subjected to a pressure through means forming a part of the machine, whereby the operator is relieved of the hand and body exertion necessary to properly apply such a pressure to iron an artic e and thereby may give his undivided attention to manipulating the iron.

It has for a further object to provide a mechanism adapted to be mounted on a suitable support and provided with such adjustments as to allow an uninterru ted movement and swing of the iron in a directions and also make it possible to reach all portions 1 of the work to be operated upon without a constant shifting of the a paratus from one end to the other of the ta le.

It further consists of other novel details of construction, all as will be hereinafter fully set forth.

Figure 1 represents a side elevation of an apparatus embodying my invention. Fig. 2 represents a detail of the iron holder. Fig. 3 represents a section through the spring pressing device. Fig. 4 represents a perspective of the supporting racket for my novel ironing apparatus. Fig. 5 represents a detail of the flat iron bracket. Fig. 6 re resents a detail of the guard arm, showingt e locking stops. Fig. 7 represents a section of a portion of a device for maintaining certain parts under tension.

For the purpose of illustrating my inven- 'tion, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be under stood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

1 designates a plate secured to a suitable supporting means as the table 2 and having lugs 3 thereon suitably positioned at the sides and top of the support 2 in order to counteract any tendency to displacement and providing a strong substantial support for hearing brackets 4, preferably integral with the plate 1 and having apertures therethrough to receive a shaft 5.

6 designates a frame having an apertured hub 7 preferably integral therewith and maintained in pro or position 011 the shaft 5 through the me 'um of the collars 8 fastened to the shaft 5 by the usual set screws 9. It will be apparent that this frame may be swung about the shaft 5 so as to sweep over an area limited only by the length of the said frame. The frame 6 is provided preferably with a forked end 10, the members of which are provided with alined apertures 11 adapt ed to receive a second shaft 12 suitably secured by collars 13 for rotation'in the a ertures 11. FiXedly secured to shaft 12 1s a collar 14 having pivoted thereto in any suitable manner, an arm 15, which in the present instance is provided with an extension 16 adapted to pass between knuckle members 17 and be secured therein by means of a stud bOlt 18.

In the preferred form the arm 15 is of tubular construction, whereby a rod 19 telescopes therewith and is fixed in any desired position by means of a wing bolt 20 screwed into rod 19 and operating in a slot 21 of the arm 15. By this means it will be clear that the length of the operating arm 15 may be varied to meet different conditions of work. The rod 19 terminates in a head 22 provided with an opening therethrough adapted to receive a spindle 23, one end of which is provided with an opening forming a holder for a supporting pin 24 secured in the holder by means of a set screw 25. The adjustment thus provided for is very essential, in view of the fact that different sized irons may be used with my apparatus, and as the handles are of difierent heights owing to the varying size of the iron, it becomes necessary to insert a separate supporting pin 24, as the occasion demands. work on the supporting table 2 and through The spindle 23 is maintained in position on the head 22 by means of collars 26 and 27, the latter having secured thereto a handle 23 with which the ironing process is carried out.

29 designates a flat iron adapted to be used in connection with my apparatus and is provided with an aperture 30 therein adapted to receive the end of the supporting rod 24, the same being held correctly positioned therein y means of an upwardly projecting bracket 31 secured to the iron and having a slot in the inside thereof adapted to cooperate with the supporting arm 24, while attachment to the parts while in operating position is provided through the interposition of a stop collar 32 affixed to supporting rod 24 and abutting the bracket 31.

33 designates a cylinder suitably supported on arm 15 and carrying therein th I compression member 34, engaging which is a follower 3'5 operated by a piston 36 secured to a piston rod 37. This rod 37 preferably passes through an opening in an extension arm 38, in the present instance fixedly secured to shaft 12 and having pivoted thereto a lever 39 to which the piston rod 37 is connected in any suitable manner to allow a slight swinging movement. The lever 39 may be fulcrumed at any of several points 40 in order to change the movement or leverage exerted on piston rod 37.

41 designates a plate secured. to extension member 38 and provided with a plurality of stops l2 thereon with which a portion 13 of the lever 39 is adapted to engage and thereby maintain the lever 39 in a retracted position to lessen the pressure effect of the compression member a l designates a guard arm positioned adjacent the plate 41 in order to prevent displacement of the lever 39 and a hook 455 is suitably connected to the lever 39 so as to engage and raise the arm 15 some distance above the table when the lever 39 has been raised to the topmost one of the stops 42. In this position the iron 29 will have been raised above the table a suitable distance to allow of removal or correct positioning of work on the supporting table.

In the operation of my device a heated iron is quickly adjusted on the supporting arm 24 and the lever 39 then brought down wardly from its normal raised position, thereby lowering the plunger 36 into the cylinder 33 and putting the spring member 34: under compression. It is then looked beneath one of the stops 42 to impart the correct pressure, whereupon the arm 15 is forced downwardly and maintains the iron 2.9 under the necessary pressure to do the pressing required. The operator grasps the handle 28, manipulates the iron over the the medium of the shafts 5 and 12 the iron may be moved in any desired manner over the table and at the same time may swing around relative to the head 22, thereby allowing a very natural and free movement in pressing. it will be further apparent that by this mechanism the operator of the iron is absolutely relieved from all fatiguing exertion relative to pressing down the iron with sufficient effect to produce a properly ironed article and may give accurate attention to the manipulation of the iron over the work.

It will be noted that the movement of the iron from one place to another on the table is a very simple sliding one and the swinging jointed members will readily take any position desired with the expenditure of very little exertion. Furthermore, the several adjustments provided make it possible to vary the length of the stroke relative to the table to change and regulate the amount of pressure exerted upon the iron and also the size of the iron to be used.

It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a device of the character described, a support, a bracket secured. thereto, a frame nivotally mounted on said bracket adapted to swing above said support, a plurality of arms pivoted to said frame, a rod slidingly mounted on one of said arms, a head secured to said rod, an iron detachably secured to said head, and means between said arms to exert a downward pressure on said iron.

2. In a device of the character described, a support, a bracket secured thereto, a frame pivotally mounted on said bracket adapted to swing above said. support, a plurahty of arms pivoted to said frame, a rod shdin-gly mounted on one of said arms, a head secured to said rod, an iron detachably secured to 120 support, a bracket secured thereto, a frame 125 pivotally mounted on said bracket adapted to swing above said support, a plurality of arms pivoted to said frame, a rod slidingly mounted on one of said arms, a head secured to said rod, an iron detachably secured to said head, a cylinder secured to one arm, a piston in said cylinder secured to the other arm, a spring interposed between said cylinder and piston to exert a downward pressure on said iron and means to regulate the ten- 10 sion of said spring.
